BLASTING DEVICE.

:recenser Specification of Letters Patent.

Patented Aug. 17, 1909.

Application filed ltarch 3, 1909. Serial No. 481,138.

provide a blasting machine wherein the articles of glassware to be treated or acted upon' are automatically shifted with relation to the blast nozzles so as to bring the whole of the surface which is to' be treated within 'the range of said nozzles.

Another object is to provide means whereby the device may be adjusted for regulating the movementof the shifting mechanism.1 And a still further objectwithin the contemplation of this invention is to provide a comparatively simple, inexpensive' and eilicient device wherein mud or thin mortar is employed as the abrading element. Other objects will be in part obvious and in part pointed out hereinafter. l

The invention accordingly'oonsists in the features of construction, combinations of elements andy 'arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the appended claims.

In the accompanying drawingswlfigure 1 is a general sectional elevation of one embodiment of this invention showing the general arrangement and formation of the various elements comprising the saine; Fig. 2 is a side elevation ofthe 'same g Fig. 3 is a section ofthe same on the line 3 3, Fig. 1; Fig. 4 is an enlarged section on the line 4 4, Fig. 1; and-Fig. 5 is an enlarged perspective View of a blast nozzle.

Referring to said drawings, in which like reference numerals designate like parts throughout the several views-1 indicates a receptacle or reservoir for containing abra- 'sive material, said reservoir having a ho pershaped lower portion and having a sli able cover 2, as shown. Leading into said reservoir is a pipe 3 for air or steam, preferably the latter, from which branch ipes 4 lead to oppositely-disposed nozzles 5 coated on opposite sides bf the path of movement ofthe rapidly by the belt 25.

l articles of ware which are suitably mounted and held upon a revoluble shaft 6.

Leading from the steam pipe 3 to a point adjacent to the bottom of the hopper is a branch pipe 7 adapted for discharging steam with considerable force for constantly agitating and mixing the thin mortar or mud 8 and, consequently, preventing to a considerable extent chance logging ofsuction pipes 9 -which'lead from points adjacent to the bottom of the reservoir to the branch pipes 4 directly in the rear-of the nozzles 5. lt wih of course be perceived that the force of the steam directedthrough the nozzles will produce a suction which will draw the mortar or mud through the pipes 9 and cause' it to be v discharged with force against th'e interposed ware.

For the purpose of moving the ware longitudinally between the nozzles 5 and consequently exposing a relatively large, or the whole, surface of the Ware to the abrading action of the blasts issuing from said nozzles, the shaft o is journaled in the forks 10 of aV support borne by a movable carriage 11. Said carriage has rollers 12 which travel upon a bed-plate 13, and fixed guide-bars 14 serve to maintain the carriage seated and to prevent displacement thereof. A pitman 15 connects said carriage to a crank-arm 16 fixed upon a shaft 17 which is journaled inA supports 18. Said shaftv 17 has Ithereon a gear-wheel 19 in mesh with a pinion 20 fixed on a second shaft 21 journaled' in said sup- )orts 1S, the last-mentioned shaft also havlng a belt-wheel 22 thereon which is connected by a belt 23 to asuitable drive-shaft 2-1 or other. main driving mechanism. An elastic h t 2 wnnects a pulley wheel Zixed on the shaft between the forks 10 to said dri eshaft 24. A slot 27 in the crank-arm 16 provides for the adjustment of the pitman 15` with relation to the shaft 17, and consequently provides means whereby the length of the stroke, of the pitman and, therefore, the length of the longitudinal movement of the shaft 6, may be regulated.

The operation of this invention, while largely apparent from the foregoing description, may be now partially and briefly'restated for the sake of clearness: The ware to be treated is mounted in any appropriate manner upon the shaft 6 which is revolved With each 'revioluyv tion of the shaft 17 on which the crank-arm;y

Iproportion of the surface of the ware subiectthrough said nozzles, a longitudinally mov- -mving saidshaft longitudinally a preder' termined distance.

vmeans for moving said shaft across the path v comprising 'in combination, a reservoir for 5f through said nozzles, a rotary shaft support -tomaticallymoving said shaft longitudinally path of the abrasive material issuing .from

Q Y v eenen 16 is carried, the carriage ll is moved for l ward and back, carrying therewith said shaft 6, such movement being 'ermitted by the elastic character of the be t 25. Theware is consequently moved forward and back past the blast nozzles, the length of the movement of said shaft 6 and, therefore, the

ed to the action of the blast, being regulated by adjustment of the pitman with relation to said crank-arm. l
